Slovenian artist Teja Krasek paints exquisite mathematically inspired designs that look like geometric mosaics. She interweaves colors and shapes to please the eye while playing with principles of symmetry, fractals, and the golden ratio. Here is her treatment of Archimedes' Square, the world's oldest documented puzzle, now turned into a beautiful work of art.
